Why are there no applications @ 1400nm?
ANSWER: HIGH LOSS!!!
1350nm to 1450nm (E-band)
traditionally no operation due to high loss.

14. E-band
Standard Fiber Partially Blocked by Water
1310 nm band
Lanes
Closed 1400 nm band
1550 nm band
•1280 to 1625nm
•highest loss at 1383nm
•loss caused by hydroxl ions in the glass
•traditional manufacturing process unable to remove these ions.
•Commonly known as “Water Peak”
•Ordinary singlemode fiber (G.652 compliant fiber) suffers from
this problem.

15. Zero Water Peak Full Spectrum fiber
Singlemode Fiber
− 9um SINGLEMODE
− G.652.C compliant
− no water peak
− removes Hydroxl ions from fiber
− Increases capacity per Fiber
− Due to elimination of water peak causing high loss
− 60% more usable wavelengths
− Maximizes support for CWDM / DWDM
− Low Cost Future Proofing for Next Generation Equipment
